Systems and methods for diffusing essential oils

ABSTRACT

Some implementations of the present invention relate to systems and methods for diffusing scents to a given location by placing a scent reservoir within a vessel including an inner chamber, a vent, and a selectively closable opening. In some cases, the scent reservoir is secured within the vessel while allowing the desired aroma to diffuse into the surrounding area through the vent. In some cases, the inner chamber comprises a wall or layer that is less permeable to the scent than is the vent. Accordingly, in some cases, the inner chamber is configured to direct the scent from the scent reservoir to the vent, which is disposed at an outer surface of the vessel. While the vessel can be any suitable object, in some cases, it is a stuffed animal. Other implementations are also described.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates generally to systems and methods for diffusing scents. In particular, some implementations of the present invention relate to systems and methods for diffusing scents to a given individual, location, or environment by placing a scent reservoir containing a scent source within a vessel including an inner chamber, a vent, and a selectively closable opening. In some such implementations, by enclosing the scent source within the vessel with the vent, a user is protected from direct contact with the scent source, and the scent is able to readily and rapidly diffuse directly from the vent and into the ambient environment.

Background and Related Art

The effective diffusion of a scent or aroma is necessary in a variety of applications. In particular, aromatherapy, deodorizing, and scent based pest control all require the diffusion of a particular scent or aroma beyond a localized scent source. One potential scent source includes essential oils, which require a diffuser or a similar means of dispersing the oils to maximize their efficacy.

Despite the popularity, utility, and widespread use of essential oils and similar scent sources, current diffusers are not necessarily without their shortcomings. By way of example, many diffusers need electricity to help dispense the aroma or scent from the diffusers through the use of sprayers, heat, fans, humidifiers, or a combination of methods that require power or mechanical movement. As a result, these diffusers often need immediate access to an electrical outlet, which often limits where they can be placed.

In some such examples, the diffusers spray a liquid scent source, or a diluted solution containing the liquid scent source, into the air in the form of a mist. While these nebulizers are an effective means of diffusing a liquid, some scent sources include synthetic chemicals that can be harmful or toxic to people, pets, and/or the environment when sprayed directly into the air.

In yet another example, some diffusers require the heating, melting, or burning of scented oils, waxes, gels, or other materials to diffuse a scent. In some cases, this heating, melting, or burning can release airborne toxins. Some of these heat based diffusers, even battery powered diffusers, can present a risk of fire and, in some designs, pose an added hazard of electrical shock. The placement of heat based diffusers is also limited oftentimes because they must be carefully located to ensure they are not near flammable materials as this can increase the risk of fire. Accordingly, current solutions are often limited in their application and/or location as they are very specific in design and purpose. Moreover, the melting or burning of scented products can also release undesirable byproducts into the air. These undesirable byproducts can be harmful to the environment and may be harmful to users that come into contact with the byproducts.

Some manufacturers have attempted to reduce the aforementioned risks and limitations. However, products from such attempts often suffer from reduced effectiveness and muted aromas. To counteract this, strong artificial scents are commonly used. However, these stronger scents can have a negative tradeoff of exposing the user (and others) to more concentrated chemicals and potential allergens.

Thus, while techniques currently exist that are used to diffuse scents, challenges still exist, including those discussed above. Accordingly, it would be an improvement in the art to augment or even replace current techniques with other techniques.

SUMMARY OF THE INVENTION

The present invention relates generally to systems and methods for diffusing scents. In particular, some implementations of the present invention relate to systems and methods for diffusing scents to a given individual, location, or environment by placing a scent reservoir containing a scent source within a vessel including an inner chamber, a vent, and a selectively closable opening. In some such implementations, by enclosing the scent source within a vessel with a vent, the user is protected from direct contact with the scent source, and the scent is able to readily and rapidly diffuse directly from the vent and into the ambient environment—in some cases, without leaving a residual scent in the vessel.

With reference to the scent reservoir, the scent reservoir can comprise virtually any suitable reservoir that can absorb, hold, and/or release a scent. In some implementations, the scent reservoir is configured to contain a scent or combination of scents which can be diffused readily and rapidly from the inner chamber to provide the desired aroma. Some examples of suitable scent reservoirs include, but are not limited to, natural, woven, non-woven, knitted, netting, or technical fabrics or materials; lava rock; bamboo based materials; polymers; ceramics; silica beads; sand; and/or any other suitable materials that can absorb, hold, and/or release a scent. Indeed, in some cases, the scent reservoir comprises wool, cotton, cellulose, and/or any other suitable material that functions as described herein. In this regard, in some particular implementations, the scent reservoir comprises wool that absorbs, holds, and releases aromas from a scent source such as a natural essential oil.

With reference to the vessel, the vessel can comprise any suitable object that is configured to receive the scent reservoir and allow for the diffusion of the scent. In this regard, some implementations of the vessel include an inner chamber, a vent, and a selectively closable opening to allow the scent reservoir to be placed within the vessel, minimize direct physical contact between the user and the scent reservoir, and dispense the scent by natural air dispersion mechanisms. Thus, in at least some implementations, the vessel is easily transportable and can be deployed for use in virtually any chosen location and for virtually any purpose because some implementations utilize natural air dispersion mechanisms and not electrical or mechanical means. In particular, in some non-limiting examples, the vessel can be: carried with the individual for aromatherapy; placed in a drawer, cupboard, and/or other location for pest control; placed into a gym bag, closet, or other location for deodorizing; placed as a decorative and scent diffusing object (e.g., an ornament on a Christmas tree); and/or otherwise be used to diffuse one or more scents.

In this regard, some examples of vessel configurations include, but are not limited to, stuffed animals, air fresheners, bracelets, calming devices, cushions, decorations, (de)odorizers, dolls, figurines, home furnishing items, jewelry, keychains, knick-knacks, novelty items, ornaments, pendants, pillows, rodent/pest control devices, seasonal decor, table-top items, toys, vehicle novelty items, aesthetically pleasing objects, and/or any other desired article for defusing a scent.

The vessel can also comprise a variety of materials to ensure the effective diffusion of a scent through the vent, while minimizing residual scent in the vessel and limiting contact between the user and the scent source. In this regard, some implementations of the vessel comprise natural, woven, non-woven, knitted, netting, synthetic, and/or technical fabrics or materials; leathers; bamboo based materials; polymers; ceramics; rubbers; woods; metals; or any other suitable material or combination of suitable materials. Indeed, in some embodiments, the vessel comprises one or more fabrics, plush fabrics, cloths, terry cloths, felts, plush felts, velboa plush fabrics, long hair plush fabrics, velvets, furs, leathers, microfibers, polyester, rayon, cotton wool, linen, flannel, canvas, silk, lace, faux fur, plush furs, plastics, polymers, metals, ceramics, and/or any other suitable material. In some cases, for instance, an outer surface of the vessel comprises one or more types of cloths or fabrics.

With reference to the inner chamber, some implementations of the inner chamber are designed to receive the scent reservoir. In this regard, an opening may extend through a surface of the vessel to provide access to the inner chamber. In some implementations, the opening is selectively closable.

With reference to the selectively closable opening, some implementations of the selectively closable opening are adjustable between an open position that allows access to the inner chamber, and a closed position that is configured to maintain the scent reservoir within the inner chamber. In some implementations, the selectively closable opening comprises a closing mechanism to provide an open and a closed position. Some examples of closing mechanisms include, but are not limited to, one or more zippers, ties, cords, clips, clamps, crimps, pins, magnets, hooks, loops, hook and loop fasteners, hooks and corresponding eyelets, catches, tabs, slots, buckles, snaps, buttons and/or any other suitable component or components that are configured to allow the vessel to be selectively closed (or sealed) and opened.

With reference to the vent, the inner chamber may extend to a vent positioned in any suitable location, including, without limitation, on a surface of the vessel. In this regard, the vent can be constructed of any suitable material that is substantially permeable and/or breathable to allow the scent to readily and rapidly diffuse from the vessel through the vent.

Indeed, in some implementations, the vent is more breathable (or scents can diffuse through the vent more rapidly) that is some material of the vessel that surrounds (or that is otherwise adjacent to) the vent. Some examples of suitable materials for the vent include, but are not limited to, natural, woven, non-woven, knitted, netting, or technical fabrics or materials; polymers; ceramics; metals; and/or any other material that allows a scent to diffuse through it. In some cases, the vent comprises one or more grids, pieces of mesh, screens, pieces of netting, relatively thin pieces of fabric, and/or any other suitable material that allows the scent to diffuse through it relatively rapidly.

Thus, in at least some implementations, the present invention extends to scent diffusing vessels comprising an inner chamber, a vent fluidly connecting the inner chamber to the outside environment, and a selectively closable opening proving selective access to the inner chamber from the outside environment.

By using the described scent diffusing vessel, scent can safely, readily, and rapidly diffuse from a scent reservoir placed within the vessel. In particular, in some implementations that lack the vent, the scent may be trapped, slowed, or muted, with reduced effectivity. In some implementations, the vent allows for the rapid changing of scents because the scent diffuses through the vent and not through the structure of the vessel, which prevents the buildup and retention of earlier scents. Thus, in at least some implementations, the same vessel is used for aromatherapy, deodorizing, pest control, for novelty purposes, and/or for a wide variety of other purposes — reducing the need for multiple scent diffusers. Likewise, in some implementations that lack the selectively closable opening, the scent reservoir may be at risk of falling out of the vessel and rendering the device inoperable, as well as exposing users or others (i.e., children or pets) to direct physical contact with the scent source. As such, in some implementations, the configuration of the vessel is specifically selected to contain the scented object securely while allowing the desired aroma to be diffused and otherwise used to maximum effectiveness.

While the systems and methods of the present invention may be particularly useful for aromatherapy, deodorizing, pest control, and novelty purposes, those skilled in the art will appreciate that the described systems and methods can be used in a variety of different applications and in a variety of different fields of use. For instance, the described systems and methods can be used in any application to readily and rapidly diffuse a scent or aroma directly into a desired environment. Additionally, while some implementations of the described systems and methods are used to diffuse essential oils, the described systems and methods can be used to diffuse any other suitable perfume, fragrance, chemical, natural materials, synthetic materials, and/or other suitable material.

These and other features and advantages of the present invention will be set forth or will become more fully apparent in the description that follows and in the appended claims. The features and advantages may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention will now be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with the summary, the detailed description, and any preferred and/or particular embodiments, examples, and variations specifically discussed or otherwise disclosed. This invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided by way of illustration only and so that this disclosure will be thorough, complete, and fully convey the full scope of the invention to those skilled in the art.

The present invention relates generally to diffusing scents. In particular, some embodiments of the present invention relate to systems and methods for diffusing scents to a given individual, location, or environment by placing a scent reservoir containing a scent source within a vessel including an inner chamber, a vent, and a selectively closeable opening. In some such embodiments, by enclosing the scent source within the vessel with the vent, the user and others are protected from direct contact with the scent source, and the scent is able to readily and rapidly diffuse directly from the vent and into the vessel's ambient environment without necessarily leaving a residual scent in the vessel.

While the scent diffusing device described herein can include any suitable feature that allow it to diffuse one or more scents (or other materials), FIGS. 1A-1B show that, in some embodiments, the described scent diffusing device 100 comprises a scent reservoir 102 and a vessel 104, wherein the vessel 104 further comprises an inner chamber 106, a vent 108, and a selectively closable opening 110. In the depicted embodiments, the selectively closable opening 110 allows the scent reservoir 102 to be placed within (and/or to be removed from) the inner chamber 106 of the vessel 104. In this regard, once the scent reservoir 102 has been placed within the inner chamber 106, the scent may be diffused by natural air dispersion mechanisms (e.g., as illustrated by the arrows labeled as 112) through the vent 108, while simultaneously preventing the scent reservoir 102 from directly contacting the user and/or absorbing into the vessel 104.

With regard to the scent reservoir 102, the scent reservoir 102 can comprise virtually any suitable object that can absorb, hold, and/or release a scent source 114 (and/or any other suitable diffusible material). In some embodiments, the scent reservoir 102 is configured to contain a scent source 114 or combination of scent sources 114 which can be diffused readily and rapidly from the inner chamber 106 to provide the desired aroma to a given individual, location, or environment. Some examples of such scent reservoirs 102 include, but are not limited to, natural, woven, non-woven, knitted, netting, synthetic, and/or technical fabrics, lava rock, bamboo based materials, polymers, ceramics, silica beads, and/or any other materials that can absorb, hold and/or release a scent. Some non-limiting examples of such include wool, cotton, cellulosic material, nylon, polymers, plastic, polyester, rayon, linen, flannel, silk, lycra, velvet, poly-cotton, yarn, string, batting, and/or any other suitable material. Indeed, as some oils and/or other scents can break down some synthetic materials, in some embodiments, the scent reservoir comprises a natural material, such as wool.

It should also be understood that the scent reservoir 102 may have any suitable size or shape for absorbing, holding, and/or release a scent (or other chemical) and fitting within the inner chamber 106. Indeed, in some embodiments, the scent reservoir 102 has a shape that is partially cuboidal, partially square, partially rectangular, spherical, elliptical, rounded, curved, polygonal, symmetrical, asymmetrical, irregular, and/or any other suitable shape or combination of shapes. Indeed, in some embodiments instead of comprising a swatch of cloth or fabric (e.g., something that can have a substantially two dimensional appearance), the scent reservoir comprises one or more balls, cubes, pyramids, prisms, and/or other suitably shaped object having more of a three dimensional appearance. In some such embodiments, the scent reservoir can further be sized and shaped such that it does not present a choking hazard for children or others.

In some embodiments, the ability to remove the scent reservoir 102 is desired for washing the vessel 104, washing the scent reservoir 102, utilizing disposable scent reservoirs 102, changing scents, replenishing the scent source 114, and/or or using the vessel for multiple applications (i.e. aromatherapy, pest control, deodorizing, and/or any other suitable application) without necessarily leaving residual scents in the vessel. However, in other embodiments, the scent reservoir 102 is not removable. In some such embodiments, the size of the selectively closable opening 110 is optionally minimized because the selectively closable opening 110 need only be large enough to allow the scent source 114 to be applied to the irremovable scent reservoir 102. In accordance with some embodiments, however, FIGS. 1A-B show that the scent reservoir 102 comprises a removable all-natural wool ball (and/or any other material of any other suitable shape and size) that can absorb, hold, and/or release a scent after contacting a scent source 114.

The scent source 114 can comprise any suitable material that is configured to allow a scent and/or another chemical to be diffused from the scent diffusing device 100. In some embodiments, the scent source 114 comprises a liquid, oil, solid, gas, vapor, wax, gel, powder, paste, and/or any other suitable material that is placed in contact with the scent reservoir 102. In this regard, in some particular embodiments, the scent source 114 comprises a mixture of fragrant natural essential oils or aroma compounds, fixatives, and/or solvents that are used to create an agreeable scent that is poured, dabbed, rubbed, dropped, placed on, absorbed in, and/or otherwise applied to the scent reservoir 102.

With regard to the vessel 104, the vessel 104 can comprise any suitable object that is configured to hold one or more scent reservoirs 102 and allow for the diffusion of the scent. In this regard, some embodiments of the vessel 104 comprise an inner chamber 106, a vent 108, and a selectively closable opening 110 that allow the scent reservoir 102 to be placed within the vessel 104, to minimize direct physical contact between the user (and/or others) and the scent reservoir 102, and to readily and rapidly dispense the scent by natural one or more air dispersion mechanisms 112.

With respect to the inner chamber 106, the inner chamber may be designed to receive the scent reservoir 102. In this regard, some embodiments of the inner chamber 106 are formed (e.g., integrally, detachably, and/or otherwise) within the body of the vessel 104. In some embodiments, inner chamber 106 comprises one or more layers 116 that define an interior cavity. In some embodiments, outer layer of the inner chamber comprises a scent permeable material. In some other embodiments, one or more layers 116 of the inner chamber 106 comprise any suitable material that is impermeable or at least substantially impermeable (i.e., does not allow air, fluid, scent, and/or another chemical to pass through it, or that does not allow air, fluid, scent, and/or another chemical to pass through it as quickly as they pass through the vent 108). In some embodiments, a substantially impermeable layer 116 defines the inner chamber 106 and/or serves as a barrier to prevent the scent from diffusing (e.g., as a liquid and/or airborne scent) into the body, stuffing, and/or structure of the vessel 104.

Some examples of suitable layer 116 materials include, but are not limited to, natural, woven, non-woven, knitted, netted, and/or technical fabrics, synthetic and/or semi-synthetic compounds made from polymers, and/or any other suitable material that may prevent the scent from diffusing into the body or structure of the vessel 104 through the layer 116. Indeed, in some embodiments, the layer comprises one or more types of: canvas, nylon, finely woven materials, plastic coated materials, polymer coated materials, polyvinyl chlorides, polyurethanes, silicone elastomer, waxes, fluoropolymers, polytetrafluoroethylenes, plastics, polymers, layers of material having one or more polymer treatments, tightly woven cottons having a one or more polymer coatings, materials that are shown (e.g., by gas chromatography-olfactory (GC-sniffing) and/or otherwise) to have reduced scent transfer, materials noted with reduced transfer of volatile organic compounds, textiles configured for chemical and/or biological protection, carbon fiber materials, materials (e.g., cotton, wool, silk, and/or any other suitable material) that are interwoven with one or more synthetic materials (e.g., one or more polymers, polyesters, and/or any other suitable synthetic materials), materials having one surface coated with one or more polymers and/or polyesters, materials having two sides coated with one or more polymers and/or polyesters, materials impregnated with one or more polymers and/or polyesters, water-resistant microfibers, hydra stretch microfibers, PVC coated nylons, one-sided laminated water resistant jersey, one- or two-sided rubber tarpaulin canvases (and/or other suitable materials), bonded natural fibrous materials, taffetas, taffetas with infused Knott backing, water-resistant polyester twills, performance soft shells woven with fleece backing, nylon Taslans, glasses, and/or any other suitable material that is configured to help cause the scent to diffuse through the vent 108, as opposed to through the layer 116 and into the vessel 104. Indeed, in some embodiments, the layer comprises a waterproof microfiber. Moreover, in some embodiments, the layer 116 of the inner chamber comprises one or more polymers, microfibers, and/or other suitable materials that substantially seal the layer and thereby help ensure that scents are diffused from the vent 108, out of the vessel, and that such scents do not permeate (and/or reduce the amount of such permeation) through the layer and into the vessel 104 (e.g., into stuffing surrounding the inner chamber). Accordingly, in some embodiments, the substantially impermeable layer helps prevent scent residue from building up in the vessel. Thus, in some cases, when one scent source is removed from the vessel 104 another can be added without unduly mixing the two scents.

In some embodiments, the inner chamber 106 optionally extends from one surface 118 of the vessel 104 to one or more other surfaces 118 of the vessel 104. In other embodiments, the inner chamber 106 only extends to one surface 118 of the vessel 104. In accordance with some particular embodiments, FIG. 1B depicts an inner chamber 106 that extends from a first end of the vessel to a second end of the vessel. In still other embodiments, the inner chamber is removable (e.g., for cleaning) and/or replaceable.

The inner chamber 106 can comprise any suitable number of inner compartments, including, without limitation, 1, 2, 3, 4, 5, 6, or more. Indeed, some embodiments, the inner chamber 106 is optionally divided into multiple compartments. In some particular embodiments, the inner chamber 106 is divided into multiple compartments by including baffling that runs through the inner chamber 106. In other embodiments, the inner chamber 106 connects to one or more internal passages that extend through a portion of the interior of the vessel 104.

With regard to the selectively closable opening 110, some embodiments of the selectively closable opening 110 are configured to create one or more openings in one or more surfaces 118 of the vessel 104. In this regard, the selectively closable opening 110 may be adjustable between an open position that allows access to the inner chamber 106, and a closed position that is configured to maintain the scent reservoir 102 within the inner chamber 106 and/or to prevent the scent reservoir 102 from contacting the user inadvertently.

In some embodiments, the selectively closable opening 110 comprises one or more closing mechanisms 120. In this regard, the closing mechanism comprises any suitable mechanism that is configured to selectively close and open. Some examples of suitable closing mechanisms 120 include, but are not limited to, one or more zippers, ties, cords, clips, clamps, crimps, pins, magnets, hooks, loops, hook and loop fasteners, hooks and corresponding eyelets, tabs, slots, buckles, snaps, buttons, and/or any other suitable method for selectively maintaining contact between to items and/or for selectively opening and/or closing (or sealing a portion of) the inner chamber 106. Indeed, in some embodiments, the closing mechanism comprises a zipper. In some embodiments, the vessel 104 optionally includes one or more flaps 122 to cover or conceal the selectively closable opening 110 for aesthetic or safety purposes. Indeed, in some embodiments, the vessel comprises one or more closing mechanisms (e.g., zippers, snaps, etc.) in addition or in place of the flaps.

With regard to the vent 108, the vent 108 may comprise any suitable object or material that is configured to diffuse the scent (and/or any other suitable chemical) from the inner chamber 106 of the vessel 104 to an individual, location, and/or environment outside the vessel 104. In this regard, the vent 108 can be constructed of any suitable material that is substantially permeable and/or breathable to allow the scent to readily and rapidly diffuse from the vessel without the necessity of heat, mechanical, or other powered means. In other words, some embodiments of the vent are more breathable than the substantially impermeable layer 116 and/or the vessel 104 surrounding the inner chamber 106. Some examples of such suitable materials include, but are not limited to, one or more rigid plastics, pliable plastics, types of cotton, types of poly cotton, pieces of wool, types of polyester, bamboo materials, meshes, screens, nettings, relatively thin pieces of cloth or fabric, wool, athletic knits, spandex, non-woven fabrics, molded plastic, perforated plastic, and/or any other suitable material that can keep the scent reservoir 102 within the inner chamber 106 while allowing the scent (or other chemical) to diffuse through the vent more quickly than through the substantially impermeable layer 116. Indeed, in some embodiments the vent comprises a piece of mesh material, a screen, a perforated material, and/or any other suitable material that allows the scent diffusing device to function as described herein.

In some cases, although the vent 108 is more scent permeable than some embodiments of the layer 116, the vent still seals a portion of the inner chamber 106 to prevent the scent reservoir 102 from being able to be removed from the vent while the selectively closable opening 110 is closed. Additionally, in some cases in which the vent is disposed at an outer surface of the vessel 104 such that the vent is at least partially surrounded by material of the outer vessel, the vent comprises a different material that the material that surrounds it. Additionally, in some embodiments, there is little to no batting, feathers, foam, and/or other stuffing disposed between the inner chamber 106 and the vent 108.

As depicted generally in FIGS. 1A-B, in at least some embodiments, the scent diffusing device 100 is easily transportable and can be deployed for use in any chosen location and for any purpose. In particular, in some non-limiting examples, the vessel 104 can be carried (and/or otherwise used) with the individual for aromatherapy; placed in a drawer, cupboard, and/or other location for pest control; placed into a gym bag, closet, car, and/or any other suitable location for deodorizing; and/or in any other suitable location and purpose because some embodiments of the diffusing device are configured to dispense the scent (or other chemical) by natural air dispersion mechanisms 112 and not necessarily by electrical or mechanical mechanisms.

Accordingly, it should be understood that the scent diffusing device 100 may be used in a variety of applications. Indeed, some configurations include, but are not limited to, air fresheners, bracelets, calming devices, cushions, decorations, deodorizers, dolls, figurines, home furnishing items, jewelry, keychains, knick-knacks, novelty items, ornaments, pendants, pillows, rodent/pest control devices, seasonal decor, stuffed animals, table-top items, toys, vehicle novelty items, aesthetically pleasing items, and/or as any other suitable item that is configured to diffuse one or more scents as described herein.

Given the variety of different configurations, it should be understood that the scent diffusing device 100 may comprise a variety of pliable, rigid, resilient, natural, synthetic, and/or other suitable materials based on the desired configuration. Some examples of suitable materials include, but are not limited to, natural, woven, non-woven, knitted, netting, or technical fabric based materials, lava rock, plastics, bamboo based materials, polymers, woods, cellulosic materials, metals, ceramics, any materials listed herein, and/or any other materials for providing aromatherapy to people and animals, for deodorizing or applying a specific odor (odorizing) to a specific location, for the purpose of pest control, for novelty use, and/or for any other suitable use.

Given the variety of different configurations, it should also be understood that the scent diffusing device 100 can comprise a variety sizes and shapes.
